adc3fd2a22 wifi: mt76: mt7921: fix kernel panic due to null pointer dereference 
Address a kernel panic caused by a null pointer dereference in the

`deflink` structure is correctly linked to the `sta` context, preventing the
null pointer dereference.

Assuming sums of values stored in variables such as sub_total_cnt

Play it safe and fix the problem by casting right hand expressions

2d5630b0c9 wifi: mt76: mt7925: fix fails to enter low power mode in suspend state 
The mt7925 sometimes fails to enter low power mode during suspend.
This is caused by the chip firmware sending an additional ACK event
to the host after processing the suspend command. Due to timing issues,
this event may not reach the host, causing the chip to get stuck.
To resolve this, the ACK flag in the suspend command is removed,
as it is not needed in the MT7925 architecture. This prevents the
firmware from sending the additional ACK event, ensuring the device
can reliably enter low power mode during suspend.

e74c0a7875 wifi: iwlwifi: dvm: Avoid -Wflex-array-member-not-at-end warnings 
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the `__struct_group()`
helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure
groups together all the members of the flexible `struct iwl_tx_cmd`
except the flexible array.

As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`.

We also want to ensure that when new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use `static_assert()`. This ensures that the
memory layout for both the flexible structure and the new tagged struct
is the same after any changes.

This approach avoids having to implement `struct iwl_tx_cmd_hdr`
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.

So, with these changes, fix the following warnings:

drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
